WINDING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 792,565, dated June 13,1905.

Application filed June 4, 1904. Serial No. 211,204.

To all 1072,0721, it may concern:

Be it known that I, SIMON WV. WVARDWELL, a citizen of the United States,residing at Providence, in the county of Providence and State of RhodeIsland, have invented new and useful Improvements in inding-Machines, ofwhich the following is a specification.

My invention relates to winding-machines, and particularly to that classof machines in which the thread-guide bears at all times during thewinding on the surface of the cop, receding from the Winding-spindle asthe yarn is built up thereon.

The object of my invention is to provide improved devices for preventingthe guide from returning toward the winding-spindle after it has beenforced out by the growing cop.

The invention is fully set forth in the following specification,illustrated by the accompanying drawings, in which Figure 1 is a frontView of the winding-machine; Fig. 2, a detail of the traverse-framedetent, being a sectional view on the line 1 1, Fig. 1; Fig. 3, a detailof the detent fingerlever, showing its relation to the traverseframe.

The machine in general is of a familiar type known to those versed inthe art as the Universal W inding-Machine. It comprises, essentially,the main frame A, supporting bearings for the winding-spindle B andcam-shaft O, the latter carrying the cam (not shown) which reciprocatesthe thread-guide D. The thread-guide slides in the traverse-frame E,which is pivoted on the cam-shaft G and adapted to swing to carry theguide away from the spindle. The traverse-frame carries a weight E belowits pivot-point which serves as acounterbalance for the frame and themechanism it carries. In order that the cop may be wound hard and iirm,it is necessary that the guide bear at all times upon the surface of thecop, and to provide for this pressure is applied to the traverse-frameto resist its movement outward from the winding-spindle. For thispurpose I prefer to make use of the devices shown at G and described inmy pending application, Serial No. 135,768, filed December 18, 1902,

in which the weighted arm a is connected to the lower arm of thetraverse-frame and tends to swing the latter to carry the guide towardthe winding-spindle.

The cop-tubes employed for winding-machines are generally formed ofpaper or straw board made inexpensively and apt to have rough irregularsurfaces. If the thread-guide were allowed to follow in and out overthis wavy surface in traversing the tube, the cop would be started withan irregular foundation and the irregularities would be magnified asmore layers were added. Also in the style of winding effected by thisvariety of machine the coils of thread cross and recross each other, andat each crossing one coil is raised above the other, so that the guideis pressed outward beyond the plane of the original coils in any onelayer. The in-and-out movement of the guide from this cause, if allowed,would also tend to accentuate the irregularities of the cop-surface; butit has been determined in practice that if the guide is prevented fromreturning toward the spindle after being once forced outward the surfaceof the cop is maintained straight and regular during the Winding.Various devices have been heretofore designed to adapt the guide toreciprocate always in a straight path parallel to the surface of thewinding-spindle; but my improved means accomplishes the desired resultwith a simple and positive mechanism.

The operation of the machine is controlled through a starting-lever J,which when shifted to start the winding is held in position by thedetent H. This latter is formed as a sector, pivoted at 72. andsupported concentric with the axis of the traverse-frame E by theextension It, bearing on the arm Z of the lever J. On the under side ofthe sector H is a V- shaped groove 9, extending throughout its entirelength. (See Fig. 2.) Extending parallel to the back of thetraverse-frame and supported in bearings in the lug f and leg 6 of theframe is a rod 6 formed with a detentarm 0, bent at right angles theretoand having an extension 6, tapered to correspond to the groove 9. At theouter end of the rod is fastened a finger-lever 7", bearing against thelug and serving to retain the rod in its bearings. Thelever f ispreferably made of sheet metal, with a portion formed to surround therod 0' and adapted to bind upon the latter when clamped with the screw7. Adjacent the top of the lever is fastened a double wire spring a bymeans of a rivet a. \Vith the lever properly adjusted the spring aengages a portion of the frame E, tending to carry the lever outward andforcing the extension (2' of the detent firmly into the groove 7. Anytendency of the frame to move backward toward the winding-spindle isresisted by the wedging of the detent in the groove; but the outwardmovement of the frame tends to swing the detent, and thereby releasesits hold on the sector. Ilt will be seen that the frame swings readilyoutward under the pressure of the growing cop on the guide, and itsmovement is only resisted by whatever pressure is applied through thedevices at (r. The inward movement of the frame, however, is preventedby the detent 0 unless the latter is released by the operator.

In removing knots, &c., and in piecing the yarn the operator frequentlymoves the traverse-frame outward as far as possible to make room for hishand between the guide and the package. hen it is desired to resume thewinding, the guide is readily returned to the winding-spindle bypressing upon the lever f to release the detent from the sector. It isimportant, however, that the guide shall not be pressed against thepackage with too much force or the latter might be injured by carelessoperators. To guard against this, I provide an arrangement whereby themovement of the frame is under perfect control of the hand upon theoperation of the finger-lever. To this end the back of the frame isformed with an extension 0, (see dotted lines, Fig. 3,) which besidesserving for the spring s to bear on provides a convenient grasping placefor the operators fingers. The most natu ral manner of operating thelever f will be with the thumb bearing against the portion a" and theforefinger pressing on the lever f. In this way agrasp of thetraverse-frame itself is insured, and it is then under easy control ofthe hand and may be moved at will to adjust the guide delicately againstthe package.

It will be seen that the devices above described are an improvement overany now in use, having the advantage of extreme simplicity, positiveaction, convenience of operation, and least liability of being impairedthrough wear.

hat I claim as my invention, and wish to secure by Letters Patent, is-

1. The combination in a winding-machine with a winding-spindle, atraversing threadguide and a frame to support the guide to move awayfrom the spindle, of a member extending in the path of the frame andhaving a taper groove, and a detent on the frame engaging said groove toresist the movement of the frame toward the spindle.

2. The combination in a winding-machine with a winding-spindle,areciprocating threadguide and a traverseframe supporting the guide tomove away from the spindle,of a member extending throughout the path ofthe frame and having a groove, and a detent hinged on the frame andadapted to be swung to engage said groove.
